SPECIFICATION forming part of Letters patent No. 601,972, dated April 5, 1898..

Application led August 6, 1897. Serial No. 647,363. (No model.)

To all whom, it mag/concern:

Be it. known that I, RUDOLPH LEONHART, J r., a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented a new and usefuly Windmill, of which the following is a speciication.

This invention relates to windmills, its object being to simplify and improve the construction thereof, whereby the windwheel may be easily and quickly turned into and out of operative position and fewer parts will' be required to make an operative device.

With this and otherobjects in view the invention consists of the several'details of construction and combination of parts', as will be hereinafter referred to, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective step-bearing 3, secured on a suitable supportl 4, which latter is perforated for the passage of the pump-rod.

5 indicates a platform secured on the upper end of the tower, through which the tubular mast 2 extends downwardly to the step-.bearing 3, and this platform is provided witha suitable ball-bearing 6 for the mast.

To the upper end of the tubular mast are secured two spaced parallel vertical arms, which lie in a vertical plane to one side of the mast, and from the upper ends of these ver:

tical arms the horizontal arms 8 extend. The arms 8 are preferably' integral with the arms 7, and to their outer ends a U-shaped frame 9 is rigidly connected. This frame preferably consists of a metal bar bent to form the upper and lower horizontal members 10 and the vertical member 11, the latterbeing secured midway its length to the ends of the arms 8.-

12 indicates bearings secured between the arms 8, and in these bearings a'shaft 13 is journaled and provided at one end with a crank 14, adapted to be connected to the pumprod l5, and at its other end, within the U- shaped frame 9, with a beveled gear 16.

17 indicates the wind-wheel, the shaft 1S of which is journaled in a bearing 19, clamped between two metal bars 2O and 21, which bars are so bent as to form another U -shaped frame ,22, the upper and lower horizontal members 23 of which are supported, respectively, by

. the upper and lower horizontal members 10 of the U-shaped frame 9. A vertical shaft 24 extends through the horizontal arms of the U-shaped frames and is supported therein in any suitable manner to permit the frame 22 to turn thereon relatively to the frame 9.

The shaft 18 projects within the frame 22 and carries a beveled pinion 25, and a beveled gear 26,' which is mounted on the shaft24 in the upper end of the U -shaped frame, meshes with the pinion 25 and the beveled gear 16 and transmits motion from the wind-wheel to the pump-rod.

27 indicates aspring which is coiled around l the lower end of the shaft 24, below the U- shaped frames, and the ends of this spring are respectively connected to the lower-horizontal arm of the'frame 9 and the lower horizontal arm of the frame 22. The arms 10 and 23 of the U-shaped frames are provided with lugs 28, which serve asstops -to preventthe horizontal arms from moving out of vertical alinement in one direction, and the normal tendency of the spring 27 is to hold the lugs 1 on one arm in engagement with the other arm and 'thereby maintain the said arms in vertical alinement, and when in this position the wind-wheel will be in operative position. To the lower horizontal arm 23 a lever 29 is secured midway its length, and this lever eX- tends diagonally across the arm, and ropes 30 and 3l are secured to its ends, which ropes respectively pass over pulleys 32 and 33, supported between the vertical arms 7, down to thelower end of the tower, where they'are adapted to be secured in any suitable manner and will be within convenient reach of IOO the operator when it is necessary to shift the wind-wheel.

When it isdesired to turn the wind-wheel the operator will release the rope 31 and pull on the rope 30, which will have the effect of turning the U-shaped framesat a right angle to each other against the force of the spring 27, and the wind-wheel will be brought around to lie parallel with the U -shaped frame 9, when by securing the rope 30 it will be maintained in this position and will be free to follow the course of the wind without being turned, as it will always present the ends of the blades toward the wind when in this position. inoperative to its operative position, the rope 30 will be released and the spring 27 will automatically throw the wheel into operative position, and by securing the rope 31 it Will be held firmly in such position.

From vthe foregoing description it Will b e seen that the parts constituting my improved windmill are few and simple and are not liable to get out of repair, that a vane is entirely dispensed with, and that by simply releasing the rope which holds the. wind-wheel i tubular mast and the wind-wheel, of two oppositely-disposed Ui-.shaped frames, one be- 1 ing pivotally supported by the other, the sup.- porting-,frame being rigidly connected to the in its inoperative position the latter.. will be automatically turned to its operative position.

It will be understood that changes in the form, proportion, and the minor detailsA of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim isr-` l. In a windmill, the Combination with the tower and the mast supported toturn axially therein, of Vframe rigidly connected to the upper end of the mast, a frame pivotally supported by the first frame and' arranged to swing horizontally7 a wind-wheel Carried by f tower, the tubular mast supported to turn f axially thelem and the pump-rod, of spaced vertical arms secured to the Lipper end of the mast, spaced horizontal arms extending from the upper ends of said vertical arms, a U- the pivoted frame and adapted to swing horizontally into and out of the Wind, and means toV turn the wind-wheel frame on its pivot and secure it in position, substantially asde- `scribed.

2. In a windmill, the combination with the tower and the mast supported to turn axially therein, of a Ufsllapod frame rigidly connected to the upper end of the. mast, a similar U- shaped wind-wheel-supporting frame, the upper and lower horizontal arms of which are respectively supported on the upper and lower horizontal arms of the first-named frame, a vertical shaft supported by the horizontal armsof the said frames and serving as apivot forr the supporting-frame, a wind-wheel carried bythe said frame, and means toturn the wind-wheel frame on its pivot and secure it in position, substantiallyl as described.

3, In awindmill, the combination with a therein, of a U, -Slio-ped fram@ rigidly connected tothe upper end of the. mast, a similar U.-

shaped frame, the upper and lower horizontal arms of which` are` respectivelg7 supported on the upper and lower arms of the firstnamed frame, a vertical shaft supported by the horizontal arms of the said frames and In order to turn the wheel from its i tubular mast and the wind-wheel, of two opserving as a pivot for the supported frame, a
